Specification of Letters Patent.

Patented Mar. 18, 1919.-

Application filed April 24. 1918. Serial No. 230.517.

To all whom it may concern.

Beit known that I, PATRICK A. MGGIRR, a citizen of the United States,residing at DeKalb, in the county of Dekalb and State of Illinois, haveinvented a new and useful Plow, of which the following is aspecification.

My invention relates to plows and particularly to a sod and stubblecutting attachment for plows.

A principal object of this invention is to provide an attachment forplows which will cut the sod or stubble immediately after the plow hasturned the slice of soil, or to be more accurate, before the plow hascom-- pletely turned over the slice. In other words, it is my object toprovide a cutting attachment which will function while the plow is stillfunctioning, i. e. which will slice the sod as it falls away from themoldboard after being turned thereby.

Another object is to provide a plow attachment which will help topulverize the soil, thereby saving further harrowing.

Other objects of this invention are to provide a simple attachment, onewhich is easily adjusted for various soil conditions, and one which isstrong and durable.

One embodiment of this invention is illustrated in the drawing whichaccompanies and forms a part of this specification. I desire it to beunderstood, however, that I contemplate making changes in many detailsin carrying out my invention, and that I do not wish to be limited to astrict adherence to the illustrated embodiment except by the appendedclaims.

In the drawing- Figure 1 is a side elevation of a plow equipped with myattachment;

Fig. 2 is a top plan view of the same.

Fig. 3 is a vertical sectional view taken on the line 33 of Fig. l andlooking in the direction of the arrow; and

Fig. 4 is a vertical sectional view on the line 44 of Fig. 3,.looking inthe direction of the arrow, parts of the plow being broken away.

Referring to the drawing, it will be seen that the numeral 1 designatesa beam of a plow, the foot or standard of which is held by bolts 2 tothe plow 3. 4 is the share or point of the plow, while 4 is themoldboard of the same. The parts so far describedare those of a plow ofordinary construction and form no part of my invention.

The sod and stubble cutting attachment comprises the bent hanger 5 andthe straight hanger 6 connected together by a bolt as at 7 and passingone on either side of the beam 1, as Fig. 3 clearly shows. The hanger 5is bent as at 8 at an angle approximating 45, forming the part 9 whichis vertical and parallel to the straight hanger 6. These hangers supportthe cutting means, indi cated generally by the numeral 10 and are inturn supported upon the beam 1 by means of a U-shaped clip or clamp.Said clip con sists of the U-shaped bracket 12 and the strap 11, whichis threaded near each end to receive the two ends of the bracket. Nuts13 unite the strap and bracket. As shown,

the clip passes around the vertical hanger 6 and clamps it tightlyagainst the plow beam, thus holding the sod-cutting means at the desiredelevation. Loosening the nuts 13 will allow the clip to be moved alongthe beam. Hence it is obvious that the hangers 5 and 6 may be held atany angle and need not be maintained in a position in the verticalplane.

The cutting means above referred to consists of a sleeve 14 mounted on arod 15 which is supported by the lower ends of the hangers 5 and 6. Thelandside end of the rod 15 has a head 16, while the furrow side isprovided with a nut 16. The sleeve 14 carries a plurality of disks 17,preferably three in number, which rotate as a unit, but four or two maybe more desirable under certain conditions. These disks are similar tothose found in the common types of disk harrows and need no furtherdescription.

The sleeve 14 is free to rotate about its bearing rod l5 and may beremoved and re placed by another sleeve of similar construction butbearing other sizes, styles or arrangements of disks. Such a removal iseffected by loosening nut 16.

As Fig. 3 shows, the hangers 5 and 6 with the rod 15, form asubstantially triangular or bow-shaped frame. A second and some whatsimilar frame is also mounted on the beam, said frame including the bars18 and 24, which are secured at one end by a clip to the beam as will bedescribed, and at the other end to the rod 15-. The bar 18'is bent at anangle of 45 at 20 to form the part 22, which engages with the plow beam.This bar is also bent in two planes at 19, as Figs. 1 and 2 indicate.Thus bar 18 rises from the part 21 and also turns toward the beam fromthat part. The part 21 is held by nut 16 shows.

while the 'part 22 is oined to the bar 24 by bolt 23 which passes overthe-plow beam. A bracing rod 25 is passed through the part 21 near thebend 19 and also through the bar 24, to which it is held by the nuts 26one on each side-ofthe-bar. This bracing rod25 adds strength andrigidity to the frame formed by the parts 18, 24, and 15 but does not inany way interfere with :the slicing action of the disks.

A U-shaped clip similar inevery respect to the clip which clamps the.hanger G-tothe beam, 'and similarly designated,;.holds the M 22. 1 hehe'i 8 fi m y-a n th ihea-m so that the former cansuffer, no displace---ment. The bar; 24isbent as at 27 between its point, of -connectionwith the bracing rod 25 and-its connection with the ,rod 15. In everyrespect-the bar24 bearsthe relation to bar 18 that. hanger 6 bears. tohanger, 5. In

Fig. 1 bar .18 hides bar 24 because 24lap pears het ameg h fe eatienaas. bar 18. Howe e as the drawingshows, bar 24 li es. almostentirely in two planes,w11er.eas l8 lies. in three plane It-willbenoticed that the-.two-j-frames above vdescribed, are both connected tothe cutting means proper and are bothslidably connected to the beam.iI-Ience by merely loosening the nuts 13 of-each clip the cutting-mechanismca-n be raised or; lowered or shifted laterally at; the willof the, user.

The disks 17 act as rotating knives. The furrow is out; by the share 4and delivered against the moldboard 4 and; the latter throws; itupward-andmurnsitz-over. j How- -,therefore, is not a deviceuwhich will.increase materially the. draftofthe plow as any attachment inevitablydoes which slices the hard ground before the share cuts the furrow.The-present invention lets the plowshare do its work first andthencatches-the furrow just as it breaks andcutsthe sod or stubble. Inorder to attain this result, the disks 17 are shaped so astoconformgenerally to-theface of the-moldboard-as, Fig. 4 In short, thedisks aresoshaped that-they cooperate with-the moldb'oard to turnthefurrow;whileslicing-it at the same time. I- prefer to place thesedisks about two inches from the face of the, moldboard,

. but. under certain conditions, they might be placed-even closerorslightly farther away to advantage. The essential point is that I thedisks be close to the moldboard and above the share, as Fig. 4 bestindicates.

My invention resides mainly in this disposit10n of the cutting blades,and it is this arrangement which I desire to protect.

This attachment, is considered to be a great aid to a farmer, especiallywhen breaking n lehdmr laaf er.efie iisznlene i or 1 even cross-plowed,considerable harrowlhg m hbe orte ehe e eith l nd-1 am -een iehfe r ps-My h ehfie jleeeen the h ndle n eeee ry e clien rlhs.
